-# LLMX with LiteLLM Configuration Guide
-
-## Quick Start
-
-### 1. Set Environment Variables
-
-```bash
-export LLMX_BASE_URL="https://llm.ai.pivoine.art/v1"
-export LLMX_API_KEY="your-litellm-master-key"
-```
-
-### 2. Create Configuration File
-
-Create `~/.llmx/config.toml`:
-
-```toml
-model_provider = "litellm"
-model = "anthropic/claude-sonnet-4-20250514"
-```
-
-### 3. Run LLMX
-
-```bash
-# Use default config
-llmx "hello world"
-
-# Override model
-llmx -m "openai/gpt-4" "hello world"
-
-# Override provider and model
-llmx -c model_provider=litellm -m "anthropic/claude-sonnet-4-20250514" "hello"
-```
-
-## Important Notes
-
-### DO NOT use provider prefix in model name
-
-❌ Wrong: `llmx -m "litellm:anthropic/claude-sonnet-4-20250514"`
-✅ Correct: `llmx -c model_provider=litellm -m "anthropic/claude-sonnet-4-20250514"`
-
-LLMX uses separate provider and model parameters, not a combined `provider:model` syntax.
-
-### Provider Selection
-
-The provider determines which API endpoint and format to use:
-
-- `litellm` → Uses Chat Completions API (`/v1/chat/completions`)
-- `openai` → Uses Responses API (`/v1/responses`) - NOT compatible with LiteLLM
-
-### Model Names
-
-LiteLLM uses `provider/model` format:
-
-- `anthropic/claude-sonnet-4-20250514`

-Check your LiteLLM configuration for available models.
-
-## Troubleshooting
-
-### Error: "prompt_cache_key: Extra inputs are not permitted"
-
-**Cause**: Using wrong provider (defaults to OpenAI which uses Responses API)
-**Fix**: Add `-c model_provider=litellm` or set `model_provider = "litellm"` in config
-
-### Error: "Invalid model name passed in model=litellm:..."
-
-**Cause**: Including provider prefix in model name
-**Fix**: Remove the `litellm:` prefix, use just the model name
-
-### Error: "Model provider `litellm` not found"
-
-**Cause**: Using old binary without LiteLLM provider
-**Fix**: Use the newly built binary at `llmx-rs/target/release/llmx`

-### Using LLMX with LiteLLM
+### Using Codex with your ChatGPT plan
 
-LLMX is powered by [LiteLLM](https://docs.litellm.ai/), which provides access to 100+ LLM providers including OpenAI, Anthropic, Google, Azure, AWS Bedrock, and more.
+<p align="center">
+  <img src="./.github/codex-cli-login.png" alt="Codex CLI login" width="80%" />
+  </p>
 
-**Quick Start with LiteLLM:**
+Run `codex` and select **Sign in with ChatGPT**. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Team, Edu, or Enterprise plan. [Learn more about what's included in your ChatGPT plan](https://help.openai.com/en/articles/11369540-codex-in-chatgpt).
 
-```bash
+You can also use Codex with an API key, but this requires [additional setup](./docs/authentication.md#usage-based-billing-alternative-use-an-openai-api-key). If you previously used an API key for usage-based billing, see the [migration steps](./docs/authentication.md#migrating-from-usage-based-billing-api-key). If you're having trouble with login, please comment on [this issue](https://github.com/openai/codex/issues/1243).
-# Set your LiteLLM server URL (default: http://localhost:4000/v1)
-export LLMX_BASE_URL="http://localhost:4000/v1"
-export LLMX_API_KEY="your-api-key"
-
-# Run LLMX
-llmx "hello world"
-```
-
-**Configuration:** See [LITELLM-SETUP.md](https://github.com/valknarthing/llmx/blob/main/LITELLM-SETUP.md) for detailed setup instructions.
-
-You can also use LLMX with ChatGPT or OpenAI API keys. For authentication options, see the [authentication docs](https://github.com/valknarthing/llmx/blob/main/docs/authentication.md).
 
 ### Model Context Protocol (MCP)
 
-LLMX can access MCP servers. To configure them, refer to the [config docs](https://github.com/valknarthing/llmx/blob/main/docs/config.md#mcp_servers).
+Codex can access MCP servers. To configure them, refer to the [config docs](./docs/config.md#mcp_servers).
 
 ### Configuration
 
-LLMX CLI supports a rich set of configuration options, with preferences stored in `~/.llmx/config.toml`. For full configuration options, see [Configuration](https://github.com/valknarthing/llmx/blob/main/docs/config.md).

+## Experimental technology disclaimer
+
+Codex CLI is an experimental project under active development. It is not yet stable, may contain bugs, incomplete features, or undergo breaking changes. We're building it in the open with the community and welcome:
+
+- Bug reports
+- Feature requests
+- Pull requests
+- Good vibes
+
+Help us improve by filing issues or submitting PRs (see the section below for how to contribute)!
+
+## Quickstart
+
+Install globally:
+
+```shell
+npm install -g @openai/codex
+```
+
+Next, set your OpenAI API key as an environment variable:
+
+```shell
+export OPENAI_API_KEY="your-api-key-here"
+```
+
+> **Note:** This command sets the key only for your current terminal session. You can add the `export` line to your shell's configuration file (e.g., `~/.zshrc`) but we recommend setting for the session. **Tip:** You can also place your API key into a `.env` file at the root of your project:
+>
+> ```env
+> OPENAI_API_KEY=your-api-key-here
+> ```
+>
+> The CLI will automatically load variables from `.env` (via `dotenv/config`).
+
+<details>
+<summary><strong>Use <code>--provider</code> to use other models</strong></summary>
+
+> Codex also allows you to use other providers that support the OpenAI Chat Completions API. You can set the provider in the config file or use the `--provider` flag. The possible options for `--provider` are:
+>
+> - openai (default)
+> - openrouter
+> - azure
+> - gemini
+> - ollama
+> - mistral
+> - deepseek
+> - xai
+> - groq
+> - arceeai
+> - any other provider that is compatible with the OpenAI API
+>
+> If you use a provider other than OpenAI, you will need to set the API key for the provider in the config file or in the environment variable as:
+>
+> ```shell
+> export <provider>_API_KEY="your-api-key-here"
+> ```
+>
+> If you use a provider not listed above, you must also set the base URL for the provider:
+>
+> ```shell
+> export <provider>_BASE_URL="https://your-provider-api-base-url"
+> ```
+
+</details>
+<br />
+
+Run interactively:
+
+```shell
+codex
+```
+
+Or, run with a prompt as input (and optionally in `Full Auto` mode):
+
+```shell
+codex "explain this codebase to me"
+```
+
+```shell
+codex --approval-mode full-auto "create the fanciest todo-list app"
+```
+
+That's it - Codex will scaffold a file, run it inside a sandbox, install any
+missing dependencies, and show you the live result. Approve the changes and
+they'll be committed to your working directory.
+
+---
+
+## Why Codex?
+
+Codex CLI is built for developers who already **live in the terminal** and want
+ChatGPT-level reasoning **plus** the power to actually run code, manipulate
+files, and iterate - all under version control. In short, it's _chat-driven
+development_ that understands and executes your repo.
+
+- **Zero setup** - bring your OpenAI API key and it just works!
+- **Full auto-approval, while safe + secure** by running network-disabled and directory-sandboxed
+- **Multimodal** - pass in screenshots or diagrams to implement features ✨
+
+And it's **fully open-source** so you can see and contribute to how it develops!
+
+---
+
+## Security model & permissions
+
+Codex lets you decide _how much autonomy_ the agent receives and auto-approval policy via the
+`--approval-mode` flag (or the interactive onboarding prompt):
+
+| Mode                      | What the agent may do without asking                                                                | Still requires approval                                                                         |
+| ------------------------- | --------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------- |
+| **Suggest** <br>(default) | <li>Read any file in the repo                                                                       | <li>**All** file writes/patches<li> **Any** arbitrary shell commands (aside from reading files) |
+| **Auto Edit**             | <li>Read **and** apply-patch writes to files                                                        | <li>**All** shell commands                                                                      |
+| **Full Auto**             | <li>Read/write files <li> Execute shell commands (network disabled, writes limited to your workdir) | -                                                                                               |
+
+In **Full Auto** every command is run **network-disabled** and confined to the
+current working directory (plus temporary files) for defense-in-depth. Codex
+will also show a warning/confirmation if you start in **auto-edit** or
+**full-auto** while the directory is _not_ tracked by Git, so you always have a
+safety net.
+
+Coming soon: you'll be able to whitelist specific commands to auto-execute with
+the network enabled, once we're confident in additional safeguards.
+
+### Platform sandboxing details
+
+The hardening mechanism Codex uses depends on your OS:
+
+- **macOS 12+** - commands are wrapped with **Apple Seatbelt** (`sandbox-exec`).
+
+  - Everything is placed in a read-only jail except for a small set of
+    writable roots (`$PWD`, `$TMPDIR`, `~/.codex`, etc.).
+  - Outbound network is _fully blocked_ by default - even if a child process
+    tries to `curl` somewhere it will fail.
+
+- **Linux** - there is no sandboxing by default.
+  We recommend using Docker for sandboxing, where Codex launches itself inside a **minimal
+  container image** and mounts your repo _read/write_ at the same path. A
+  custom `iptables`/`ipset` firewall script denies all egress except the
+  OpenAI API. This gives you deterministic, reproducible runs without needing
+  root on the host. You can use the [`run_in_container.sh`](../codex-cli/scripts/run_in_container.sh) script to set up the sandbox.

+| `codex completion <bash\|zsh\|fish>` | Print shell completion script       | `codex completion bash`              |
+
+Key flags: `--model/-m`, `--approval-mode/-a`, `--quiet/-q`, and `--notify`.
+
+---
+
+## Memory & project docs
+
+You can give Codex extra instructions and guidance using `AGENTS.md` files. Codex looks for `AGENTS.md` files in the following places, and merges them top-down:
+
+1. `~/.codex/AGENTS.md` - personal global guidance
+2. `AGENTS.md` at repo root - shared project notes
+3. `AGENTS.md` in the current working directory - sub-folder/feature specifics
+
+Disable loading of these files with `--no-project-doc` or the environment variable `CODEX_DISABLE_PROJECT_DOC=1`.
+
+---
+
+## Non-interactive / CI mode
+
+Run Codex head-less in pipelines. Example GitHub Action step:
+
+```yaml
+- name: Update changelog via Codex
+  run: |
+    npm install -g @openai/codex
+    export OPENAI_API_KEY="${{ secrets.OPENAI_KEY }}"
+    codex -a auto-edit --quiet "update CHANGELOG for next release"
+```
+
+Set `CODEX_QUIET_MODE=1` to silence interactive UI noise.
+
+## Tracing / verbose logging
+
+Setting the environment variable `DEBUG=true` prints full API request and response details:
+
+```shell
+DEBUG=true codex
+```

+
+### Custom instructions
+
+You can create a `~/.codex/AGENTS.md` file to define custom guidance for the agent:
+
+```markdown
+- Always respond with emojis
+- Only use git commands when explicitly requested
+```
+
+### Environment variables setup
+
+For each AI provider, you need to set the corresponding API key in your environment variables. For example:
+
+```bash
+# OpenAI
+export OPENAI_API_KEY="your-api-key-here"
+
+# Azure OpenAI
+export AZURE_OPENAI_API_KEY="your-azure-api-key-here"
+export AZURE_OPENAI_API_VERSION="2025-04-01-preview" (Optional)
+
+# OpenRouter
+export OPENROUTER_API_KEY="your-openrouter-key-here"
+
+# Similarly for other providers
+```

+
+## FAQ
+
+<details>
+<summary>OpenAI released a model called Codex in 2021 - is this related?</summary>
+
+In 2021, OpenAI released Codex, an AI system designed to generate code from natural language prompts. That original Codex model was deprecated as of March 2023 and is separate from the CLI tool.
+
+</details>
+
+<details>
+<summary>Which models are supported?</summary>
+
+Any model available with [Responses API](https://platform.openai.com/docs/api-reference/responses). The default is `o4-mini`, but pass `--model gpt-4.1` or set `model: gpt-4.1` in your config file to override.
+
+</details>
+<details>
+<summary>Why does <code>o3</code> or <code>o4-mini</code> not work for me?</summary>
+
+It's possible that your [API account needs to be verified](https://help.openai.com/en/articles/10910291-api-organization-verification) in order to start streaming responses and seeing chain of thought summaries from the API. If you're still running into issues, please let us know!
+
+</details>
+
+<details>
+<summary>How do I stop Codex from editing my files?</summary>
+
+Codex runs model-generated commands in a sandbox. If a proposed command or file change doesn't look right, you can simply type **n** to deny the command or give the model feedback.
+
+</details>
+<details>
+<summary>Does it work on Windows?</summary>
+
+Not directly. It requires [Windows Subsystem for Linux (WSL2)](https://learn.microsoft.com/en-us/windows/wsl/install) - Codex is regularly tested on macOS and Linux with Node 20+, and also supports Node 16.
+
+</details>
+

+
+## Zero data retention (ZDR) usage
+
+Codex CLI **does** support OpenAI organizations with [Zero Data Retention (ZDR)](https://platform.openai.com/docs/guides/your-data#zero-data-retention) enabled. If your OpenAI organization has Zero Data Retention enabled and you still encounter errors such as:
+
+```
+OpenAI rejected the request. Error details: Status: 400, Code: unsupported_parameter, Type: invalid_request_error, Message: 400 Previous response cannot be used for this organization due to Zero Data Retention.
+```
+
+You may need to upgrade to a more recent version with: `npm i -g @openai/codex@latest`
+
+---
+
+## Codex open source fund
+
+We're excited to launch a **$1 million initiative** supporting open source projects that use Codex CLI and other OpenAI models.
+
+- Grants are awarded up to **$25,000** API credits.
+- Applications are reviewed **on a rolling basis**.
+
+**Interested? [Apply here](https://openai.com/form/codex-open-source-fund/).**
+
+---
+
+## Contributing
+
+This project is under active development and the code will likely change pretty significantly. We'll update this message once that's complete!
+
+More broadly we welcome contributions - whether you are opening your very first pull request or you're a seasoned maintainer. At the same time we care about reliability and long-term maintainability, so the bar for merging code is intentionally **high**. The guidelines below spell out what "high-quality" means in practice and should make the whole process transparent and friendly.
+
+### Development workflow
+
+- Create a _topic branch_ from `main` - e.g. `feat/interactive-prompt`.
+- Keep your changes focused. Multiple unrelated fixes should be opened as separate PRs.
+- Use `pnpm test:watch` during development for super-fast feedback.
+- We use **Vitest** for unit tests, **ESLint** + **Prettier** for style, and **TypeScript** for type-checking.
+- Before pushing, run the full test/type/lint suite:
+
+### Git hooks with Husky
+
+This project uses [Husky](https://typicode.github.io/husky/) to enforce code quality checks:
+
+- **Pre-commit hook**: Automatically runs lint-staged to format and lint files before committing
+- **Pre-push hook**: Runs tests and type checking before pushing to the remote
+
+These hooks help maintain code quality and prevent pushing code with failing tests. For more details, see [HUSKY.md](./HUSKY.md).
+
+```bash
+pnpm test && pnpm run lint && pnpm run typecheck
+```
+
+- If you have **not** yet signed the Contributor License Agreement (CLA), add a PR comment containing the exact text
+
+  ```text
+  I have read the CLA Document and I hereby sign the CLA
+  ```
+
+  The CLA-Assistant bot will turn the PR status green once all authors have signed.
+
+```bash
+# Watch mode (tests rerun on change)
+pnpm test:watch
+
+# Type-check without emitting files
+pnpm typecheck
+
+# Automatically fix lint + prettier issues
+pnpm lint:fix
+pnpm format:fix
+```
+
+### Debugging
+
+To debug the CLI with a visual debugger, do the following in the `codex-cli` folder:
+
+- Run `pnpm run build` to build the CLI, which will generate `cli.js.map` alongside `cli.js` in the `dist` folder.
+- Run the CLI with `node --inspect-brk ./dist/cli.js` The program then waits until a debugger is attached before proceeding. Options:
+  - In VS Code, choose **Debug: Attach to Node Process** from the command palette and choose the option in the dropdown with debug port `9229` (likely the first option)
+  - Go to <chrome://inspect> in Chrome and find **localhost:9229** and click **trace**
+
+### Writing high-impact code changes
+
+1. **Start with an issue.** Open a new one or comment on an existing discussion so we can agree on the solution before code is written.
+2. **Add or update tests.** Every new feature or bug-fix should come with test coverage that fails before your change and passes afterwards. 100% coverage is not required, but aim for meaningful assertions.
+3. **Document behaviour.** If your change affects user-facing behaviour, update the README, inline help (`codex --help`), or relevant example projects.
+4. **Keep commits atomic.** Each commit should compile and the tests should pass. This makes reviews and potential rollbacks easier.
+
+### Opening a pull request
+
+- Fill in the PR template (or include similar information) - **What? Why? How?**
+- Run **all** checks locally (`npm test && npm run lint && npm run typecheck`). CI failures that could have been caught locally slow down the process.
+- Make sure your branch is up-to-date with `main` and that you have resolved merge conflicts.
+- Mark the PR as **Ready for review** only when you believe it is in a merge-able state.
+
+### Review process
+
+1. One maintainer will be assigned as a primary reviewer.
+2. We may ask for changes - please do not take this personally. We value the work, we just also value consistency and long-term maintainability.
+3. When there is consensus that the PR meets the bar, a maintainer will squash-and-merge.
+
+### Community values
+
+- **Be kind and inclusive.** Treat others with respect; we follow the [Contributor Covenant](https://www.contributor-covenant.org/).
+- **Assume good intent.** Written communication is hard - err on the side of generosity.
+- **Teach & learn.** If you spot something confusing, open an issue or PR with improvements.
+
+### Getting help
+
+If you run into problems setting up the project, would like feedback on an idea, or just want to say _hi_ - please open a Discussion or jump into the relevant issue. We are happy to help.
+
+Together we can make Codex CLI an incredible tool. **Happy hacking!** :rocket:
+
+### Contributor license agreement (CLA)
+
+All contributors **must** accept the CLA. The process is lightweight:
+
+1. Open your pull request.
+2. Paste the following comment (or reply `recheck` if you've signed before):
+
+   ```text
+   I have read the CLA Document and I hereby sign the CLA
+   ```
+
+3. The CLA-Assistant bot records your signature in the repo and marks the status check as passed.
+
+No special Git commands, email attachments, or commit footers required.
+
+#### Quick fixes
+
+| Scenario          | Command                                          |
+| ----------------- | ------------------------------------------------ |
+| Amend last commit | `git commit --amend -s --no-edit && git push -f` |
+
+The **DCO check** blocks merges until every commit in the PR carries the footer (with squash this is just the one).
+
+### Releasing `codex`
+
+To publish a new version of the CLI you first need to stage the npm package. A
+helper script in `codex-cli/scripts/` does all the heavy lifting. Inside the
+`codex-cli` folder run:
+
+```bash
+# Classic, JS implementation that includes small, native binaries for Linux sandboxing.
+pnpm stage-release
+
+# Optionally specify the temp directory to reuse between runs.
+RELEASE_DIR=$(mktemp -d)
+pnpm stage-release --tmp "$RELEASE_DIR"
+
+# "Fat" package that additionally bundles the native Rust CLI binaries for
+# Linux. End-users can then opt-in at runtime by setting CODEX_RUST=1.
+pnpm stage-release --native
+```
+
+Go to the folder where the release is staged and verify that it works as intended. If so, run the following from the temp folder:
+
+```
+cd "$RELEASE_DIR"
+npm publish
+```
+
+### Alternative build options
+
+#### Nix flake development
+
+Prerequisite: Nix >= 2.4 with flakes enabled (`experimental-features = nix-command flakes` in `~/.config/nix/nix.conf`).
+
+Enter a Nix development shell:
+
+```bash
+# Use either one of the commands according to which implementation you want to work with
+nix develop .#codex-cli # For entering codex-cli specific shell
+nix develop .#codex-rs # For entering codex-rs specific shell
+```
+
+This shell includes Node.js, installs dependencies, builds the CLI, and provides a `codex` command alias.
+
+Build and run the CLI directly:
+
+```bash
+# Use either one of the commands according to which implementation you want to work with
+nix build .#codex-cli # For building codex-cli
+nix build .#codex-rs # For building codex-rs
+./result/bin/codex --help
+```
+
+Run the CLI via the flake app:
+
+```bash
+# Use either one of the commands according to which implementation you want to work with
+nix run .#codex-cli # For running codex-cli
+nix run .#codex-rs # For running codex-rs
+```
+
+Use direnv with flakes
+
+If you have direnv installed, you can use the following `.envrc` to automatically enter the Nix shell when you `cd` into the project directory:
+
+```bash
+cd codex-rs
+echo "use flake ../flake.nix#codex-cli" >> .envrc && direnv allow
+cd codex-cli
+echo "use flake ../flake.nix#codex-rs" >> .envrc && direnv allow
+```

+# Codex CLI (Rust Implementation)
+
+We provide Codex CLI as a standalone, native executable to ensure a zero-dependency install.
+
+## Installing Codex
+
+Today, the easiest way to install Codex is via `npm`:
+
+```shell
+npm i -g @openai/codex
+codex
+```
+
+You can also install via Homebrew (`brew install --cask codex`) or download a platform-specific release directly from our [GitHub Releases](https://github.com/openai/codex/releases).
+
+## Documentation quickstart
+
+- First run with Codex? Follow the walkthrough in [`docs/getting-started.md`](../docs/getting-started.md) for prompts, keyboard shortcuts, and session management.
+- Already shipping with Codex and want deeper control? Jump to [`docs/advanced.md`](../docs/advanced.md) and the configuration reference at [`docs/config.md`](../docs/config.md).
+
+## What's new in the Rust CLI
+
+The Rust implementation is now the maintained Codex CLI and serves as the default experience. It includes a number of features that the legacy TypeScript CLI never supported.
+
+### Config
+
+Codex supports a rich set of configuration options. Note that the Rust CLI uses `config.toml` instead of `config.json`. See [`docs/config.md`](../docs/config.md) for details.
+
+### Model Context Protocol Support
+
+#### MCP client
+
+Codex CLI functions as an MCP client that allows the Codex CLI and IDE extension to connect to MCP servers on startup. See the [`configuration documentation`](../docs/config.md#mcp_servers) for details.
+
+#### MCP server (experimental)
+
+Codex can be launched as an MCP _server_ by running `codex mcp-server`. This allows _other_ MCP clients to use Codex as a tool for another agent.
+
+Use the [`@modelcontextprotocol/inspector`](https://github.com/modelcontextprotocol/inspector) to try it out:
+
+```shell
+npx @modelcontextprotocol/inspector codex mcp-server
+```
+
+Use `codex mcp` to add/list/get/remove MCP server launchers defined in `config.toml`, and `codex mcp-server` to run the MCP server directly.
+
+### Notifications
+
+You can enable notifications by configuring a script that is run whenever the agent finishes a turn. The [notify documentation](../docs/config.md#notify) includes a detailed example that explains how to get desktop notifications via [terminal-notifier](https://github.com/julienXX/terminal-notifier) on macOS.
+
+### `codex exec` to run Codex programmatically/non-interactively
+
+To run Codex non-interactively, run `codex exec PROMPT` (you can also pass the prompt via `stdin`) and Codex will work on your task until it decides that it is done and exits. Output is printed to the terminal directly. You can set the `RUST_LOG` environment variable to see more about what's going on.
+
+### Experimenting with the Codex Sandbox
+
+To test to see what happens when a command is run under the sandbox provided by Codex, we provide the following subcommands in Codex CLI:
+
+```
+# macOS
+codex sandbox macos [--full-auto] [--log-denials] [COMMAND]...
+
+# Linux
+codex sandbox linux [--full-auto] [COMMAND]...
+
+# Windows
+codex sandbox windows [--full-auto] [COMMAND]...
+
+# Legacy aliases
+codex debug seatbelt [--full-auto] [--log-denials] [COMMAND]...
+codex debug landlock [--full-auto] [COMMAND]...
+```
+
+### Selecting a sandbox policy via `--sandbox`
+
+The Rust CLI exposes a dedicated `--sandbox` (`-s`) flag that lets you pick the sandbox policy **without** having to reach for the generic `-c/--config` option:
+
+```shell
+# Run Codex with the default, read-only sandbox
+codex --sandbox read-only
+
+# Allow the agent to write within the current workspace while still blocking network access
+codex --sandbox workspace-write
+
+# Danger! Disable sandboxing entirely (only do this if you are already running in a container or other isolated env)
+codex --sandbox danger-full-access
+```
+
+The same setting can be persisted in `~/.codex/config.toml` via the top-level `sandbox_mode = "MODE"` key, e.g. `sandbox_mode = "workspace-write"`.
+
+## Code Organization
+
+This folder is the root of a Cargo workspace. It contains quite a bit of experimental code, but here are the key crates:
+
+- [`core/`](./core) contains the business logic for Codex. Ultimately, we hope this to be a library crate that is generally useful for building other Rust/native applications that use Codex.
+- [`exec/`](./exec) "headless" CLI for use in automation.
+- [`tui/`](./tui) CLI that launches a fullscreen TUI built with [Ratatui](https://ratatui.rs/).
+- [`cli/`](./cli) CLI multitool that provides the aforementioned CLIs via subcommands.

 ## Core primitives
 
 We have 3 top level primitives:
-- Thread - a conversation between the LLMX agent and a user. Each thread contains multiple turns.
+- Thread - a conversation between the Codex agent and a user. Each thread contains multiple turns.
 - Turn - one turn of the conversation, typically starting with a user message and finishing with an agent message. Each turn contains multiple items.
 - Item - represents user inputs and agent outputs as part of the turn, persisted and used as the context for future conversations.
 
 ## Thread & turn endpoints
 
-The JSON-RPC API exposes dedicated methods for managing LLMX conversations. Threads store long-lived conversation metadata, and turns store the per-message exchange (input → LLMX output, including streamed items). Use the thread APIs to create, list, or archive sessions, then drive the conversation with turn APIs and notifications.

 ### Quick reference
 - `thread/start` — create a new thread; emits `thread/started` and auto-subscribes you to turn/item events for that thread.
 - `thread/resume` — reopen an existing thread by id so subsequent `turn/start` calls append to it.
 - `thread/list` — page through stored rollouts; supports cursor-based pagination and optional `modelProviders` filtering.
 - `thread/archive` — move a thread’s rollout file into the archived directory; returns `{}` on success.
-- `turn/start` — add user input to a thread and begin LLMX generation; responds with the initial `turn` object and streams `turn/started`, `item/*`, and `turn/completed` notifications.
+- `turn/start` — add user input to a thread and begin Codex generation; responds with the initial `turn` object and streams `turn/started`, `item/*`, and `turn/completed` notifications.
 - `turn/interrupt` — request cancellation of an in-flight turn by `(thread_id, turn_id)`; success is an empty `{}` response and the turn finishes with `status: "interrupted"`.
